The Mandrake Hotel, located a short walk from Oxford Circus, has been known for subversive decadence since its opening in 2018. The vibe is equal parts hedonistic and spiritual, although perhaps those are one in the same. The downstairs bar and restaurant buzz at night and its commonplace to bump into actors, artists or musicians in the dimly lit hallways.

Now, the hotel is launching a new spiritual wellbeing concierge service. This means that guests can pre-book a variety of spiritual wellbeing sessions, such as the Soul Connector - a sound bath which claims to tantalise the senses and clear blockages as you go on a cosmic journey. Fully tailored experiences and group sessions are also available. The Mandrake calls upon Londons top healers to perform these treatments in guests rooms or suites, where a menu card is installed, describing each of the different options. If you are unsure which to book, the spiritual concierge is available for consultation.

This new offering is an opportunity to rest and reinvigorate the soul, not just the body. When you are travelling or in the city, you get caught up with things, says Alex Holbrook, head of spiritual wellbeing at The Mandrake. We have a spiritual spa instead of a classic spa, and its a haven for complete renewal and rebalancing. Spirituality can be another tool in your box alongside the gym, nutrition and therapy.

The spiritual experiences are best takenin one of the hotels suites, which are lavish and comfortable, with plenty of room for your spiritual guide to set-up. Mine was performed in the Penthouse Suite, on the third floor of the hotel. All white and marble with a calming mix of soft and hard materials, there was a massage table with a shaggy, fur-like cover and pillows set up by the bed. A series of pastel-coloured glass and quartz bowls and instruments were laid out on the floor, next to a worn, palm-sizedbook with angels on its cover.

The spiritual guide assigned to treat me with a Spiritual Awakening was Josie Danielle, an intuitive energy healing and sound expert who is usually based in Shoreditch, but on speed dial with The Mandrake for such appointments. Her voice was soft and dream-like and she was swaddled in a snug pale knitted jumper and loose capris.

I was invited to take a seat opposite her and, after asking me a series of personal questions, she explained what I was about to experience: sound therapy to settle my body, reiki to work on it on an energetic level, and 'light language' for healing and to call me into my soul (I will explain this later). As a first-timer, I was told that if my thoughts started to spiral, I must come back to the mantra, I am present. I am ready to receive, recite it in my head and breathe deeply.

She noted, as we sat talking,that my arms were crossed in front of my womb - a sign of protection brought on by past trauma, and diagnosed me with a need for womb work, to heal the energy blockages in that area of my body. This is a concept that was totally foreign to me, but I resolved to be as open to the process as possible, and would advise any other beginners to adopt the same approach.

After this initial briefing and diagnosis, I was ushered onto the table, where Iwas covered with a blanket and a weighted lavender eye mask was placed on my face. Now everything was black and the session began with what I can only describe as an expanding bubble of pure sound - this was the sound therapy portion of the session. It resonated and grew as Josiecircled the crystal singing bowls with a quartz wand, interspersed with the occasional bong-g-g from a gong. I felt slight vibrations through my body. If anything, it was really quite relaxing.

Then the manually-created sound transitioned to a relaxing pre-recorded tune. I smelled incense being wafted over my body - the next stage was reiki, which seeks to redirect energy and clear blockages. I could not see what was happening above me, but I felt Josies presence as she worked on unblocking my energy. Every now and again she would come closer and touch an area of my body with a series of light taps. As all of this happened, I drifted in and out of consciousness. Not asleep, but it felt as if I had floated into another place - something I have never experienced before.

Then I heard Josie speaking in what sounded like an ancient tongue. This turned out to be light language, a cosmic language that is said to distribute sound and energy to convey messages. Instead of knowingly speaking, like you would in English, it is said to be interpreted by the heart - what came out of her mouth is an expression of feeling and has no translation.

With the tinkle of some chimes, the experience came to an end, and I sat up, woozy. I had expected to either feel nothing, or to be subject to some vast spiritual awakening - neither of those things happened. I just felt odd, like something inside me had been moved. I was told that this meant it had worked, that I must drink a lot of water, and that I might experience flu-like symptomsat some point overthe next five days before coming into my full power thereafter.

There is no classic spa to relax in at the Mandrake, but the lavish bathroomsthe suites mean you hardly notice. A huge standalone bathtub was my evening refuge before room service arrived from Yopo, the hotel restaurant. I was extraordinarily hungry after the session and devoured the offering, finally crashing into myfour poster bed for some rest.

That night, my mind was active. I felt troubled and found it hard to sleep, and the next day I started to feel tired and unwell, just like Josie had predicted. This is termed a healing crisis. When the energy is rebalanced within you and it feels like youve got the flu, says Holbrook. Its something you experience when theres a buildup of energy you need to shift, like an emotional blockage.

This is said to be common for first timers, because of the backlog, and less intense going forward. I have no idea really if this was to do with the session or not, and there is no way of really telling, but after one week I was back on top form.

I wont postulate about spirituality and belief systems - each to their own - because thats not the point. As my guide said, all that is required is an openness to the experience. If you are accustomed to such treatments, as I suspect a good portion of the hotels artistic clientele is, then this is an incredibly luxurious environment in which to experience them. If you are not, it feels like a safe place to begin. If you are sceptical, then think of it this way: taking an hour to tune into yourself surely cant be a bad thing.

Private spiritual wellbeing sessions are available in all rooms, starting from 150. Rooms at The Mandrake start at 430, suites from 830 and 4,000 for the Penthouse; themandrake.com
